The following sentence is culled from the August 27 New Yorker article on Aaron Copland. (Ok, so I am behind in my reading.)

"In the thick of the group was the composer Nicolas Nabokov, a friend of Stravinsky's and a cousin of Vladimir Nabokov's, who had written for Serge Digahilev's Ballets Russes in the nineteen-twenties and then . . . ."

Do you agree with me that the 's on Stravinsky and Nabokov is incorrect? We could say "Nicolas Nabokov, Stravinsky's friend and Nabokov's cousin" or "Nicolas Nabokov, a friend of Stravinsky and a cousin of Nabokov" but we don't need both do we?

It looks like the famous proof readers and fact checkers are slipping up.

Bnj, I agree with you completely. Seems to me in the phrase "a friend of Stravinsky's", of has already rendered the 's superfluous. I suspect this is idiom that maybe grew out of a friend of mine/his but bad grammar.

(tangent: why isn't it a friend of him instead of his?)

Melissa, I dunno, whether spelled out or numerals is to me just alternate styles but in the latter would far prefer 1920s, being a shameless absolutist about segregation of plurals and apostrophes.
The New York Times and I will continue to butt heads on this until they see the error of their way's.

I hear this as an informal, conversational style, where singular or mass nouns may be saddled with plural esses. as in: "Nicolas saved a bunch on composition paper by buying it in bulk from Walmarts." /shudder/

I have met several well-bred and well-educated people who affect this style.

Aye, and more's the pity.

I'm still seeing this as an extension of friend of mine/of hers/ of his, supposing that friend of me / of him /of her failed to make the team as awkward because we prefer s-possessive and therefore despise the of-possessive construction. Then, having inserted the possessive pronouns mine/his/hers/theirs, we extend in speech to stretch as far as a friend of Stravinsky's from the prior habit. Harmony at the expense of logic.
At least so it seems to I.

I thought that Starbucks is non-denominational...

Certainly it's not non-dominational.

My vote is for Starbuckses, unaesthetic as that be, though I'd protest that the singular might should be Starbuck's, depending on how they intended the derivation of their own name, which would render Starbuck'ses. I don't like the looks of that It's Tim Horton's all over again.

This is why I drink Peet's.

Yes, on second read, it surely works as "in bulk from (some of the) Walmarts", multiple instances of one Mal-War.. uh I mean Wal-Mart.
Unbow thy head, Gailr, I stand corrected
